Explanation:
Water vapor inside magma increases its explosiveness.
true or fasle
Answer: True.
Explanation: When the water vapor bubbles try to rise they are impeded by the linkage of silica chains in the magma and can rise only slowly. The rapid change in confining pressure as the magma body rises to the surface causes the dissolved water vapor bubbles to expand and escape explosively.

given that cells can't store app for long periods of time, how do they store energy
Answer:
Given that cells can't store ATP for long periods of time, how do they store energy? Instead of storing ATP, cells tend to store energy as fats, oils, or starches. These are very large molecules and, as a result, do not have as great an effect on osmotic potential.

Which event occurs prior to speciation?
A) Different species share the same space.
B) A major change on earth takes place.
C) A population is divided.
D) Organisms of different populations join together.
Answer: C.
Explanation:
I hope this helps plz tell me if its wrong so i can fix it :)
The event that occurs prior to speciation is that a population is divided, which is Option C, as when a population is divided by a geographic barrier such as a mountain range, river, or sea, then this type of speciation takes place.
What is speciation?Speciation is the process by which a single ancestral species gives rise to two or more descendant species, and it occurs when populations of the ancestral species become separated and evolve independently, accumulating genetic differences over time by a physical or geographical barrier along with mutation, genetic drift, or natural selection that separates a population into two or more groups that are no longer able to interbreed leads to speciation.
Hence, the event that occurs prior to speciation is that a population is divided, which is Option C.

In Holstein cattle the spotting of the coat is due to a recessive gene, while a solid-colored coat is dominant. Two heterozygous solid animals are crossed. What would be the expected genotypes and phenotypes of the offspring?
Answer:
In Holstein cattle when two heterozygous animals are crossed for the characteristic coat color, the offspring will be individuals with solid coat and spotted coat in a 3:1 ratio.
Explanation:
Since in Holstein cattle the solid color coat is dominant (S), and the spotted coat is recessive (s), each heterozygous individual has the genotype Ss.
The result of crossing two individuals of Holstein cattle heterozygous can be seen in Punnet's Square:
Ss X Ss
Alleles S s
S SS Ss
s Ss ss
Genotypes
Ss 50%SS 25%ss 25%Ratio of genotypes SS:Ss:ss is 3:1:1
Phenotypes
Individuals with solid color coat 75% (50% Ss and 25% SS). Individuals with a spotted coat 25%.Ratio solid color:spotted color 3:1
Optimum germination conditions differ between species. Sometimes this depends on the evolutionary history of the plant species. One species has higher germination rates when the seeds are exposed to soil with ash present. This is an example of _______________.
Answer:
seed dormancy
Explanation:
Seed dormancy represents an evolutionary adaptation capable of preventing seed germination. Seed dormancy enables to overcome unfavorable periods for germination, thus being critical for plant survival. In this regard, it has been shown that in plants living in fire-prone ecosystems (such as, for example, montane forest species), seed germination may be triggered by ash after fire, which is required to break seed dormancy.
Why are recessive traits not seen even though they are present in the alleles?
Answer:
Because if the dominant trait (D) is present, it will in a way, overpower the recessive trait (r), and show the dominantly present trait physically but in the alleles, there might be blue in there also but be overpowered for ex: dominant brown eyes with a blue recessive trait so most likey if you have brown since it takes over

an increase in nitrates available for plants to use
an increase in nitrates from animal wastes
d
Answer:
The correct answer is - a decrease in nitrogen compounds available to organisms.
Explanation:
Nitrogen fixation is the process that involves the atmospheric nitrogen and converts into a nitrogen compound that can easily be consumed by the organism as nitrogen is one of an essential part of life.
Nitrogen fixation is carried out by the microorganism like nitrogen-fixing bacteria like azotobactor. If these bacteria were destroyed then there will be a decrease in the nitrogen compounds that are consumed by the organism as there is no more nitrogen fixation takes place.

why is the cell membrane called the fluid mosaic model? quick if you can please
Answer:
The fluid mosaic model of the cell membrane is how scientists describe what the cell membrane looks and functions like, because it is made up of a bunch of different molecules that are distributed across the membrane. ... The movement of the mosaic of molecules makes it impossible to form a completely impenetrable barrier.
Explanation:
The cell membrane is called the fluid mosaic model because proteins are arranged as a mosaic of particles that can penetrate inwards and even completely pass through the bilayer.
According to this fluid mosaic model, membranes consist of a lipid bilayer (essentially a double layer of phospholipids) in which various proteins are embedded.
The lipid bilayer is the base of the membrane, proteins are normally found "dissolved" in the lipid bilayer, they act as mediators or facilitators of almost all the functions of the membrane, either by transporting specific molecules.It also highlights that the membranes are fluid, dynamic and their components mobile, a very important characteristic that allows the existence of transitory interactions.Finally, this model of the membrane structure proposes that the arrangement of its components is asymmetric and they can have numerous associated carbohydrates.Therefore, we can conclude that the cell membrane is called the fluid mosaic model because proteins are arranged as a mosaic of particles that can penetrate inwards and even completely pass through the bilayer..

As a team of explorers travels southward from the North Pole into Canada, they encounter a dense forest of pines and other coniferous
evergreens. They leave the forest before the winter, which is long and cold. Which of these biomes has the team visited?
o A. temperate grasslands
B. Northwest coniferous forest
C. tropical dry forest
O
D. boreal forest (taiga)
Answer:
It's D
Explanation:
Among the options, the name of the biome that the team visited is known as boreal forest (taiga). Thus, the correct option for this question is D.
What is Biome?A biome may be defined as a very large ecosystem that is tunning in nature in a very unmanaged way. It may also be characterized as a very large area that is characterized by a particular type of vegetation. Some examples of biomes may include tropical rainforests, coral reefs, grasslands, etc.
According to the context of this question, taiga (boreal forests) are the types of coniferous forests that are located below the tundra in the biome triangle. These types of biomes may have a dense forest of pines and other coniferous evergreens. They leave the forest before the winter, which is long and cold. They generally possess temperatures lower than the temperare or tropical forests.
Therefore, the name of the biome that the team visited is known as boreal forest (taiga). Thus, the correct option for this question is D.

In general, microtubules disassemble and consequently pull the chromatids to the ends of the spindle during ____.
Answer: The options are not given, here are the options.
.a.prophase
b.prometaphase
c.metaphase
d.anaphase
e.telophase
The correct option is C.
Metaphase.
Explanation:
It is metaphase because during metaphase, the chromosomes lined up together and the two sister chromatids join to a particular spindle fiber. The microtubules them bring the sister together chromatids from the opposite spindle poles. The kinetochore microtubules capture the sister chromatids back and forth til they are able to form alignment along the equator of the cell which is called the equatorial plane.
